Answer:
0.416moles
Explanation:
Using the formula;
number of moles = mass ÷ molar mass
Molar mass of CO2 = 12 + 16(2)
= 12 + 32
= 44g/mol
According to the information in this question, there are 18.3g of CO2
number of moles (n) = 18.3/44
= 0.4159
= 0.416moles of CO2
Answer:
0.2M NaOh
Explanation:
there are 0.2 mol of NaOH in 8.0 g. (8.0/40) =0.2. Molarity = mol/L = 0.2M.
