Answer:
NH₃
M = n/V(L)
0.844 mol (Both numbers have 3 significant figures so the result has 3 significant figures as well)
Explanation:
Step 1: Given and required data
- Volume of solution (V): 375. mL
- Molar concentration of the solution (M): 2.25 M
- Chemical formula for ammonia: NH₃
Step 2: Calculate the moles (n) of ammonia (solute)
Molarity is equal to the moles of solute divided by the liters of solution.
M = n/V(L)
n = M × V(L)
n = 2.25 mol/L × 0.375 L = 0.844 mol (Both numbers have 3 significant figures so the result has 3 significant figures as well)
If there is any unused Chemicals left in the container it should be properly disposed and chemicals taken out of the original container should not be poured back into the container because it can be <span>contaminated</span>
Answer:
condensation
Explanation:
The process of a gas becoming a liquid is called condensation.
Salt because it's a solid and helium and nitrogen are gases.
Water is a liquid because it's form can change.
350 nm because the magnesium reacts very aggressively toward these kind of situations.
