Answer:
1.07 g of water.
Explanation:
A reaction between an acid and a base makes water and a salt as product.
Our reaction is:
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Reactants are the acid and the base. Which is the limiting?
2.9 g . 1mol /98 g = 0.0296 moles of acid
3.53 g . 1mol / 40 g = 0.088 moles of base
2 moles of base react to 1 mol of acid
0.088 moles may react to (0.088 . 1)/2 = 0.044 moles of acid
And we only have 0.0296, sulfuric acid is the limiting
Ratio is 1:2. 1 mol of acid can produce 2 moles of water.
Our 0.0296 moles may produce (0.0296 . 2) /1 = 0.0592 moles of water.
We convert moles to mass:
0.0592 mol . 18g /mol = 1.07 g
The main function of the right side of your heart is to collect blood from the body and pump it to the lungs.
Answer: To find the molar mass of a substance, use the formula:
where: mm is molar mass
g is mass of substance in grams
M is morality
Substitute in the known values and solve like an algebra problem.
The density of acetone at RTP is 0.7845 g cm-3, volume = mass/density SO 38.9/0.7845 = 49.58572... cm^3 (ml)
