Answer from: briashia

15 g of CaCo₃

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

CaO + CO₂ —> CaCo₃

From the balanced equation above,

1 mole of CaO reacted to produce 1 mole of CaCo₃.

Next, we shall determine the number of mole of CaCo₃ produced by the reaction of 0.15 mole of CaO. This can be obtained as follow:

From the balanced equation above,

1 mole of CaO reacted to produce 1 mole of CaCo₃.

Therefore, 0.15 mole of CaO will also react to produce 0.15 mole of CaCo₃.

Finally, we shall determine the mass of 0.15 mole of CaCo₃. This can be obtained as follow:

Mole of CaCo₃ = 0.15 mole

Molar mass of CaCo₃ = 40 + 12 + (16×3)

= 40 + 12 + 48

= 100 g/mol

Mass of CaCo₃ =?

Mole = mass / Molar mass

0.15 = Mass of CaCo₃ / 100

Cross multiply

Mass of CaCo₃ = 0.15 × 100

Mass of CaCo₃ = 15 g

Thus, 15 g of CaCo₃ were obtained from the reaction.

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.
