Answer to Question #91162 in Physical Chemistry for Jenny

Question

If weight of calcium containing 1mole of atoms is 40grams.Then what is the weight of carbon containing same number of atoms as in 10 grams of calcium.

Answer 1

Solution.

If one mole of calcium contains 40 grams of calcium, then 10 grams:

$$x = \frac{10 \times 1}{40}$$

x = 0.25 mole

$$m(C) = n(C) \times M(C)$$

M(C) = 12 g/mole

m(C) = 0.25 * 12 = 3 g

Answer:

m(C) = 3 g
