Chemistry

Musya8 [376]3 years ago

Answer:

The answer is: B

Explanation:

The reason for this is because when a rock is underwater (the river, in this case), the water runs across it non-stop until the rock is removed from the water. The only way it can be polished if it is submerged under the water for quite some time (years and years).

I hope this helped! :))

What is the molar mass of an element?
Vesnalui [34]

The answer is: the mass of 6.02 x 1023 representative particles of the element.

The base SI unit for molar mass is kg/mol, but chemist more use g/mol (gram per mole).

For example, molar mas of ammonia is 17.031 g/mol.

M(NH₃) = Ar(N) + 3 · Ar(H) · g/mol.

M(NH₃) = 14.007 + 3 · 1.008 · g/mol.

M(NH₃) = 17.031 g/mol.

The molar mass (M) is the mass of a given substance (in this example ammonia) divided by the amount of substance.
