Plants need oxygen to survive.
Molarity (M) is moles over liters (moles/liters), so convert grams to moles using the molar mass of MgO and then divide the moles of MgO over the liters given.
So it would look like this:
Step 1: 62.5 g MgO x (1 mole MgO/40.31 g MgO) = 1.55 mol MgO
Step 2: 1.55 mol MgO/1.5 L = 1.03 M MgO
Answer:
0.033 M
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V1) = 250 mL
Molarity of stock solution (M1 ) = 0.10 M
Volume of diluted solution (V2) = 750 mL
Molarity of diluted solution (M2) =.?
Thus, we can obtain the molarity of the diluted solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.1 × 250 = M2 × 750
25 = M2 × 750
Divide both side by 750
M2 = 25/750
M2 = 0.033 M
Therefore, the molarity of the diluted solution is 0.033 M.
Answer:
Yes.
Explanation:
Wasting household water does not ultimately remove that water from the global water cycle, but it does remove it from the portion of the water cycle that is readily accessible and usable by humans. Also, "wasting" water wastes the energy and resources that were used to process and deliver the water.
