How many grams of H3PO4 are in 234 mL of a 2.5 M solution of H3PO4?
motikmotik

Answer:

57 grams of H3PO4

Explanation:

M= moles/ liters

convert mL to L

234 mL x 1L/1000mL = 0.234L

Rearrange the Molarity formula to solve for moles.

moles= MxL

moles= 2.5M x 0.234L

moles= 0.585 mol

Use the molar mass of H3PO4 to get to grams

0.585 mol x 97.994 grams/1 mol = 57.326 grams of H3PO4

round to two sig figs for 57 grams

If an area has high air pressure and low humidity, what type of weather will it most likely have?
elixir [45]

Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.

I hope that this helps! :D

Electron affinity is the measure of the attraction of an electron toward an isolated gaseous atom. When an electron is added to
zhuklara [117]

False

Explanation:

Electron affinity is negative when energy is absorbed and it is positive when energy is released.

Electron affinity is defined as the energy released in adding an electron to a neutral atom in the gas phase.

It is a measure of the readiness of an atom to gain an electron.

In a reaction where energy is released, electron affinity is usually positive. These reactions are called exothermic reactions.

Endothermic reactions in which energy is absorbed have negative electron affinity values.
