Use dimensional analysis to solve the following two problems. Show the expression setup and cancel units in the whiteboard area, below. Be sure to include ALL units in the setup.

what volume is occupied by 0.3 moles of any gas at STP?

 

use the correct number of significant figures for your final answer. 

 

exmaple is attached and significant figure rules.

Given #liters PRACTICE mole-volume conversions X Conversion Factor 22.4 L 1 mole 1 mole 22.4 L ions, showing the complete nction, you may work your solution in ure of it and upload the picture using Resulting Unit moles Stoichiometry #1 How many liters are in 2.5 moles of hydrogen (H₂) at STP? 22.4 LH₂ 1 mole-H 2.5 moles H 2 56 L H₂

» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant. This is true whether the zeros occur before or ofter the decimal point. 237 has three significant figures. 1.897 has four significant figures. 39,004 has five significant figures. 5.02 has three significant figures. 0.008 has one significant figure. 0.000416 has three significant figures. 140 has two significant figures. 75,210 has four significant figures. 620.0 has four significant figures. 19.000 has five significant figures. For multiplication and division problems, the answer should be rounded to the same number of significant figures as the measurement with the least number of significant figures.
