If 250 mL of a solution with a 0.5 M is diluted to 850 mL, what is its new molar

Question

If 250 mL of a solution with a 0.5 M is diluted to 850 mL, what is its new molarity? 0.43 M 0.15 M 0.50 M 6.25 M Why are nuclear power plants not in danger of a nuclear explosion? They don't use any nuclear material. The enrichment of uranium remains too low for an explosion. They don't tend to use uranium, at least not those built in the United States. There is a risk, although a small one. of an explosion. What happens to elemental metals when they react in a redox reaction? They typically lose electrons. They typically gain electrons. They neither gain nor lose electrons. There is not enough information in the question to tell.

Explanation / Answer

34)
use dilution formula
M1*V1 = M2*V2
1---> is for stock solution
2---> is for diluted solution

M1*V1 = M2*V2
0.5 M* 250 mL = M*850 mL
M = 0.15 M
