Na2CO3(g) + 2HCl(aq) → 2NaCl(aq) + H2O(l) + CO2(g) How many moles of sodium trioxocarbonate…

A.

1.000 mole

B.

0.100 mole

C.

0.010 mole`

D.

0.111 mole

Correct Answer: Option C

Explanation

(frac{C_A V_A}{C_BV_B} = frac{a}{b})

(frac{0.05 times 10}{C_B times 25} = frac{2}{1})

50CB = 0.5

CB = (frac{0.5}{50} = frac{1}{100})

= 0.01
