Your question is about chemistry, not calculus.
Convert the volume of gas released (at STP) to moles. That would be 0.407/22.4 = 0.0182 moles. 1 g of Ca is 1/40 = 0.0250 moles. Get the ratio from those numbers and round it off. It will be one of the 4 choices
At STP, 1.00 g of calcium is placed into an acidic solution, and 407 mL of hydrogen gas is collected. What is the ratio of moles of calcium consumed to moles of hydrogen produced?
a)1.37:1.00
b)1.00:1.64
c)0.928:1.00
d) 0.500:1.00
Is the answer A, if so, can you explain the process.
