Answer:
The answer to your question is: a. Hydrogen-1
Explanation:
Hydrogen-1 (1.07 u)
Hydrogen-2 (2.02 u)
Hydrogen-3 (3.01 u)
Periodic table says that H has an atomic mas of 1.008
Then, the reported atomic mass is closer to the mass of the smaller isotope, so Hydrogen-1 must be present in larger percentage.
Answer:
A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
Explanation:
A mineral is naturally formed, inorganic, solid, with a fixed chemical composition, and crystalline structure. A rock at the surface of the Earth would need to be weathered down into sediments.

The gram-formula mass means that the mass of one mole molecule. Then you just need to calculate the elements together. So the gram-formula mass of (NH4)3PO4 is equals to (14+4)*3+31+16*4= 149g/mol. So the answer is (c)
<em><u>Unit conversion is very important because the rest of the world other than three contries uses the metric system. So, converting unitsis important in science because it uses the metric system. The metric system aremeasurements like cm, m, l, mL, etc.</u></em>
