Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
Well,there is 1000 grams in 1kg. So 42 grams into kg is 0.042. Therefore 42kg is bigger.
42 g = about 0.0926 pounds.

just short of a mole. moles is mass/molar mass. mass is 42, molar mass is 44. 42/44
Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
nominally 42 grams
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Density = (mass) divided by (volume) = (42) divided by (7) = 6 grams per cm3 . Next time, it'll be a lot easier if you just have your teacher contact us directly.
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
The average Aluminum can has a mass of roughly 14 grams. Then a Steel can has 2/3 more or 42 grams.
The mass of an object does not depend on gravitational pull. Their mass would still be 42 g on the moon. (By the way, that's one small person, with the mass of about 3 empty soda cans...)
42 grams is 1.48 ounces.
42 grams of water is approximately 2.963 tablespoons.
Well,there is 1000 grams in 1kg. So 42 grams into kg is 0.042. Therefore 42kg is bigger.
