The amount of moles is directly proportional to the volume of the gas under constant temperature and pressure. That is the statement of Avogadro's law. The equation is:

V1n2 = V2n1

<em>Where V is volume and n are moles of 1, initial state and 2, final state of the gas</em>

That means, right option is:

Sodium bicarbonate is sometimes used to neutralize acid spills. If 2.0 L of 1.0 M H2SO4 is spilled, what mass of sodium bicarbon

UkoKoshka [18]

Answer:

168.0 g

Explanation:

First thing, write a balanced chemical equation:

$H_{2}SO_{4}+ 2NaHCO_{3} ----> Na_{2}SO_{4} + 2H_{2}O+2CO_{2}$

n(H2SO4) = concentration * volume

= 1.0 M * 2.0 L

= 2.0 mol

According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?

mass (NaHCO3) = number of moles * molar mass

= 2.0 mol * 84.0065 g/mol

= 168.0 g
