Answer: C) The mass stays constant as it changed from a liquid to a gas
Explanation: Mass stays constant, it's never destroyed or created. It follows the law of conservation of mass.
Answer:
1.5L of NaNO3 must be present
Explanation:
<em>That contains 200g of sodium nitrate. Round to 2 significant digits</em>
To solve this question we need to convert the mass of NaNO3 to moles using its molar mass (85g/mol). With the moles and the molar concentration we can find the volume in liters of the solution:
<em>Moles NaNO3:</em>
200g * (1mol / 85g) = 2.353 moles NaNO3
<em>Volume:</em>
2.353 moles NaNO3 * (1L / 1.60moles) =
<h3>1.5L of NaNO3 must be present</h3>
