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

Chemistry

motikmotik2 years ago
5 0

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

When the equation Al2(SO4)3 + NaOH + Al(OH)3 + Na2SO4 is correctly balanced, what is the coefficient of Al(OH)3?
nevsk [136]
The balanced chemical formula should be Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4

Therefore the coefficient of Al(OH)3 is 2!

Hope that helps :)

A copper coin with a mass of 6.30 grams changes temperature in the sunshine from 20.0°C to 32.0°C. How much energy is transferre
mote1985 [20]

Answer:

The energy transferred is  28.5  j

calculation

energy is calculate  MCΔT  formula  where,

M(mass)= 6.30  grams

C(specific heat capacity)= 0.377 j/g

ΔT(change in temperature)= 32.0c- 20 c= 12 c

Energy is therefore= 6.30 g   x 0.377  j/g /c x   12 c =28.5 j

What is the name of this hydrocarbon?
Cerrena [4.2K]

Answer:

C. 2-methylpropane

Explanation:

There are rules guiding the naming of hydrocarbons. Some of the rules are:

1.) The longest continuous chain is the parent chain:

The longest chain here is made up of 3-carbon atoms which is a propane compound

2.)The carbon atoms are numbered in the parent chain to indicate where branching or substitution takes place.

Here, it is in the second carbon atom in propane.

The branched group is methyl- which is a methane molecule that has lost a hydrogen atom.

This makes ths name of the compound to be:

2-methylpropane
