There are 0.54 moles of sodium carbonate are contained by  57.3 grams of sodium carbonate.

we can calculate number of moles in a compound by dividing number of grams of compound by the molar mass of the compound.
molar mass of sodium carbonate = 105.987 g/mol
now, 57.3 / 105.987 = 0.54 moles

julsineya [31]

Answer:

0.10 moles of oxygen produced by the reaction of 0.10 of water.

Explanation:

The photosynthesis reaction is given by :

6CO_2(g)+6H_2O(l)\rightarrow C_6H_{12}O_6(aq)+ 6O_2(g)

Moles of water = 0.10 mole

According to reaction, 6 moles of water gives 6 moles of oxygen gas,then 0.10 moles of water will give :

\frac{6}{6}\times 0.10 mol=0.10 mol of oxygen gas

0.10 moles of oxygen produced by the reaction of 0.10 of water.

What is the pOH of a solution that has a hydronium ion concentration [H3O+] of 8.26 x 10–5 M?
kirill115 [55]

Answer:

9.92

Explanation:

Since we are given the concetration of H+ we can find the ph by taking the negative log and then subtracting the ph from 14 to give us pOH

-log(8.26e-5) = pH= 4.08

pOH= 14-4.08

pOH= 9.92
