Step 1
Steps to follow to solve the problem:
- Note down the mass of chalk before writing the name.
- Note down the mass of chalk after writing the name.
- To find the mass of chalk used, use the formula (Mass of chalk used = mass of chalk before writing the name - mass of chalk after writing the name)
- Use the formula of no. of moles to calculate the no. of moles of chalk used.
Calculate the mass of chalk before writing the name and after that.
Mass of the chalk before sitting the name = 10 gram
Mass of the chalk After writing the name = 9.70 gram
