The air mass in the classroom is 〔 kg 〕, which is higher than your mass 〔 big 〕 and 〔 small 〕. A and B are two equal height cylinders with equal mass. If the bottom area of a is three times that of B, how many times the density of a is that of B We need 400 grams of alcohol. We don't need a balance. We only need a measuring cylinder. We should measure the volume of alcohol to be [] CM & # 179;
