The question doesn't make sense, 40g weighs 40g. Do you mean what does 40g equate to in an other system of measures?
They both have the same mass, however their weight is different. Since the 40 g rock has more density it would have more weight.
Weight(W)=mass(M)* acceleration due to gravity(g) which is =9.8ms^2 therefore,weight of 40kg is w=40 * 9.8 w=392N
40kgs equates to 88.1 (88.1849) pounds.
2.5lbs (2.5 pounds) is a weight equal to 1.134 kilograms or 40 ounces.
Well in weight referring to pounds? If that's so Answer: 441 g = 0.972238 lb, almost 1 pound.
First take the weight in pounds and multiply it by 453.59. The resulting number is the weight in grams. In this case the answer is 18144 grams.
The molar weight of NaOH is approx. 40 g/molSo 12.0 g of NaOH would be approx 12/40 = 0.3 mol NaOH
We need:The atomic weight of Argon (Ar), which is 39.948. We will round to 39.9.Avocado's Number, we'll use 6.02 * 1023(40 g Ag) / (39.9 g/mol) * ( 6.02e23 atom/mol ) = 6.04 * 1023 atoms AgAlternatively, if you used 40 g as the atomic weight for Ar, you could just use Avocado's Number since (40 g / 40 g/mol = 1 mol )
about 3 g

2.5 g
Atomic Weight of Calcium = 40 Atomic Weight of Chlorine = 35.5 Therefore, 1 mole of CaCl2 => 40 + 2 (35.5) = 111 g 0.74 moles of CaCl2 => 0.74 (111) = 82.14 g
4 g of helium is equivalent to 1 mole of helium

The vast majority of substances in the universe. Exceptions are NaOH for example.
