I'm assuming false but really have no clue
Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
<u>Explanation:</u>
The properties and behavior of many solutions depend not only on the nature of the solute and solvent but also on the concentration of the solute in the solution. Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:

Therefore, Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
Answer:
NaNH₂₀
Explanation:
0.5 mol Na, 0.5 mol N, and 10 mol H
To obtain the empirical formulae, we find the mole ratio between the elements and this is done by dividing all through by the smallest mol (0.5)
Na = 0.5 / 0.5 = 1
N = 0.5 / 0.5 = 1
H = 10 / 0.5 = 20
The mole ratio is used to write the empirical formulae. It is given as;
NaNH₂₀
