My guess would be choice D
Answer:
first question is 178 g of sodium phosphate dihydrate. second question is 0.25 mL
Explanation:
To know the number of grams from the number of moles
. 1 mol is equal to 178 g. Second question mL of the stock is obtained from
.
Answer:
t = 2.01 s
Vf = 19.7 m/s
Explanation:
It's know through the International System that the earth's gravity is 9.8 m/s², then we have;
Data:
- Height (h) = 20 m
- Gravity (g) = 9.8 m/s²
- Time (t) = ?
- Final Velocity (Vf) = ?
==================================================================
Time
Use formula:
Replace:
Everything inside the root is solved first. So, we solve the multiplication of the numerator:
It divides:
The square root is performed:

Final Velocity
use formula:
