Answer:
The answer is
<h2>0.35 g</h2>
Explanation:
The mass of a substance given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 0.253 mL
density = 1.38 g/mL
Substitute the values into the above formula and solve for the mass
We have
mass = 1.38 × 0.253 = 0.34914
We have the final answer as
<h3>0.35 g</h3>

When nitric acid is added to water, the concentration of hydronium ions would increase since the nitric acid dissociates into ions, the hydronium ions and the nitrate ions. Hope this answers the question. Have a nice day. Feel free to ask more questions.
CO₂ ₍g₎ + 2H₂ ₍g₎ ---------> CH₃OH ₍g₎
So in order to answer this question you have to have a good understanding of moles in an equation. We know that mole often exist in ratios that is denoted by the value used to balance the equation ('mole ratio'). Thus from the equation we can tell that H₂ has twice the amount of moles CO₂ or CH₃OH does. As such:
- reactant with most moles is H₂
- raectant with least moles is CO₂
- the limiting reagent is H₂
