Calculate the mass percent of HOCH 2CH 2OH in a solution made by dissolving 3.2 g of HOCH 2CH 2OH in 43.5g of water.

Explanation:

Hello,

In this case, we are asked to compute the by mass percent for the given 3.2 g of ethylene glycol in 43.5 g of water. In such a way, since the by mass percent is computed as follows:

Whereas the solute is the ethylene glycol and the solvent the water, therefore we obtain:

Best regards.

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

i'm assuming that the correct answer is indeed the first one/ "a"..
