A cylinder has the following dimensions: radius = 3.7 cm and height = 6.5 cm. If the mass of the cylinder is 40.67 g, calculate the density in g/cm'. (V = trh) Cylinder

At stp, what is the volume of 1 mole of co2?

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
