Rubbing alcohol is 70.% isopropyl by volume. How many ml of isopropyl alcohol are in a 1 pint (473 ml) container? I think the answer is 330 ml, but I need help setting the equation up.
A gas sample contains 4.0 g of CH4 and 2.0 g of He. What is the volume of the sample at STP? I think the answer is 17 L, is this right?
V= nRT/P. I converted 4.0 g and 2.0 g to moles and then added them together to get n.
