A, milligrams because rice is very small therefore you'd need to use a very small unit of measurement.
Answer:
you are correct
Explanation:
i double checked u are correct :D
Answer:
Ca₃N₂
Explanation:
The empirical formula is the simplest whole-number ratio between moles of each element present in a molecule.
Thus, we need to convert mass of each atom to moles and find the ratio between these as follows:
<em>Moles N:</em>
1.46g * (1mol / 14.0067g) = 0.104moles
<em>Moles Ca:</em>
6.27g * (1mol / 40.078g) = 0.156moles
The ratio between Moles N and moles of Ca is:
0.156moles / 0.104 moles = 1.5
That means there are 1.5 moles of Ca per mole of N. As empirical formula must be given in whole numbers:
There are 3 moles of Ca per 2 moles of N.
Empirical formula is:
<h3>Ca₃N₂</h3>
