What is the mass of 37 mL but has the density of 0.79 g/mL

From the information given, it is not clearly stated that the substance is a liquid but because the measurement has been indicated that it is 37ml. then we will assume this is a liquid. The density of the liquid is 0.79g/ml.

mass = density * volume

mass = 0.79g/ml * 37ml

mass = 0.79 * 37

mass = 29.23

Therefore the mass is 29.23 grams.

Mass is directly proportional to volume and density. If either density or volume increases then mass increases also.
