i took this from my notes- so whatever aligns with that. sorry if this didnt help but i think its genuinely c heating
1066.7 ml of the stock solution must start with, preparing 2.00 L of a 0.800 M NaNO3 solution.
<h3>What is volume?</h3>
Volume is the space occupied by a three-dimensional object.
By the formula 
M1 is the initial molarity, 1.5 M
M2 is the final molarity, 0.800 M
V1 is the initial volume
V2 is the final volume, 2.00 L
Putting the values in the equation

Thus, the initial volume is 1066.7 ml

The question is incomplete , the complete question is;
The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.
Wt-296 = 24.6622
Answer:
The atomic mass of Wt-296 is 195.9464 amu.
Explanation:
1 amu is defined as 1 by twelfth of the carbon-12 mass.
Mass of an isotope Wt-296 = 24.6622
Mass of an isotope Wt-296 in amu = M


The atomic mass of Wt-296 is 195.9464 amu.
