Which formula can be used to calculate the molar mass of ammonia (NH3)?

Vesnalui [34]

Answer: The correct answer is Option C.

Explanation:

Molar mass is defined as the sum of the atoms present in a compound each multiplied with the number of atoms present in it.

For a compound $A_xB_y$

The molar mass will be = $[(x\times \text{Molar mass of A})+(y\times \text{Molar mass of B})]$

So, for the given compound $NH_3$ ,

The molar mass will be = $[(1\times \text{Molar mass of Niyrogen})+(3\times \text{Molar mass of Hydrogen})]$

Hence, the correct answer is Option C.

Which answer choice best describes the difference between folded mountains and fault-block mountains?

melamori03 [73]

The answer is; C

In folding, when segments of Earth's crust are bent and doubled over, the sediments in between are form folds, since they are forced into a smaller space. This also occurs in converging plates boundaries.

Block Mountains occur when stress due to compression in the crust causes the hanging wall between a fault to move up relative to the footwall.
