Start by writing out molar mass of each component:
1) NaOH= 22.99+16+1.01 --> 40
2) Na₃PO₄= (22.99)3 + 94.97 + 64 --> 227.94
3) NaNO₃= 22.99 + 14 + 48 --> 84.99
Now compare the mass of sodium with the rest of the substances:
1) (22.99/40)100%= 57.475%
2) (68.97/227.94)/100%= 30.25%
3) (22.99/84.99)/100%= 27.05%
As seen, the ordered list is: Sodium hydroxide, sodium phosphate and sodium nitrate.

A.) true
Because the rocks are formed near lava so the texture would be smooth
Answer:To calculate the Molarity of a 70 wt. % Nitric Acid the number of moles of HNO 3 present in 1 liter of acid needs to be calculated. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413
