Answer:
1.09 moles of NaOH
Explanation:
First of all, to calculate moles, you need to find the molar mass of NaOH.
Let us first find the molar mass of NaOH then.
Na = 23.0 amu
O = 16.0
H = 1.0
They are 1 nitrogen atom, 1 oxygen atom, and one hydrogen atom.
So do this.
23.0(1) + 16.0(1) + 1.0(1) = 40 g/mol.
Now use dimensional analysis to show your work
43.5 g of NaOH * 1 mol of NaOH / 40 g/mol of NaOH
The grams cancel out.
43.5 / 40.0 = 1.0875
Use sig figs and round the answer to the nearest hundredths place.
1.0875 = 1.09
So the final answer is 1.09 moles of NaOH
Hope it helped!

Covalent. The two hydrogen atoms share their electrons such that both outer shells are filled.
Total mass of carbon must be decreasing in different step of carbon cycle because matter is conserved in the processes and reactions of carbon cycle. Carbon is a matter and it is the major constituent of living organisms.
Carbon cycle refers to processes where carbon move from the atmosphere to the biosphere and Earth and then back to the atmosphere.
It involves processes of using and reusing carbon again and again and it's conservation.
Carbon is an organic matter found in living organisms and total mass of carbon reduces because it is a matter that is conserved.
Carbon is released from that atmosphere, use for photosynthesis, plants and animals consume the plants. They defecate , respirate and carbondioxide is released during respiration.
Therefore,Total mass of carbon must be decreasing in different step of carbon cycle because because matter is conserved in the processes and reactions of carbon cycle. Carbon is a matter and it is the major constituent of living organisms.
