The water at the gas-collecting port is assumed to be 25 degrees C, but it is actually 15 degrees C. How will this error affect the reported mass of aluminum in the sample?

This comes from an Aluminum Analysis lab in which hydrogen gas resulting from the reaction between aluminum and 6M HCl is collected over water.
