PLease i need help with these questions **Transcription for Educational Website:**---**Question:**What is the percent of N in \( N_2H_4 \)?**Interface:**- Show Your Work [Button]**Response Box:**- A blank text box is provided for entering the answer.- A calculator icon is available beside the text box for users who need to perform calculations.---**Explanation:**The text presents a chemistry-related question asking for the percentage composition of nitrogen (N) in the chemical compound hydrazine (\( N_2H_4 \)). Users are encouraged to show their work by clicking the "Show Your Work" button, indicating a structured approach to problem-solving. The adjacent response box is provided for users to input their calculated answer, with a calculator tool available for assistance in the calculations.Calculating the percent composition typically involves finding the molar mass of the compound and using it to determine the relative contribution of each element. This type of activity aligns with learning outcomes in chemistry education that focus on understanding molecular composition and chemical calculations. ### Calculate the Formula Mass of \( \text{Mo}_2(\text{CO}_3)_3 \) to Two Decimal PlacesThis exercise involves calculating the formula mass (molecular weight) of the compound \( \text{Mo}_2(\text{CO}_3)_3 \). Here are the steps and tools provided to complete this task:![Show Your Work Button]1. **Step-by-Step Calculation**: - Click the "Show Your Work" button to open a detailed step-by-step guide on how to calculate the formula mass of the compound. - Follow the instructions to calculate the atomic masses of each element present in the compound. - Summarize the total formula mass by adding the respective atomic masses according to the number of each atom in the formula.2. **Input Your Answer**: - There is a designated text box where you can input your final answer. - Next to the text box, there is a "Submit" button indicated by a keyboard icon. Click this button after entering your answer to submit it for evaluation.#### Detailed Breakdown:- **Mo (Molybdenum)**: Atomic mass approximately 95.95.- **C (Carbon)**: Atomic mass approximately 12.01.- **O (Oxygen)**: Atomic mass approximately 16.00.The compound consists of:- 2 Mo atoms- 3 CO3 groups (each consisting of 1 C and 3 O atoms)### Calculation:1. Calculate the individual contributions of Mo, C, and O atoms.2. Multiply these atomic masses by their respective quantities in the compound.3. Sum the total masses to get the formula mass, rounding it to two decimal places.This approach enables students to understand the composition and calculate the molecular weight of chemical compounds accurately.- Example: - \( \text{Mo}_2(\text{CO}_3)_3 \) - \( = 2 \times 95.95 + 3 \times (1 \times 12.01 + 3 \times 16.00) \)Input your final calculated value in the provided text box and submit to check your accuracy.

3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industrial strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume of vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the first minute of each reaction, and he records the data below.
