A metal that would be magnetic is nickel
Answer:
M = No.of moles of solute / Volume of solution in litres
HBr: H = 1 x 1 = 1 Br = 1 x 80
Molar mass : 81 g / mol
a. n = 27.7% / 100 =0.277 g / (81 g / mol) = 0.0034 mol
density = 1.24 g/ml ; D= m / v
b. 65.32 ml x 1 L / 1000 mL = 0.065 L
c. M= n / V
= 0.0034 mol / 0.065 L
M= 0.052 mol / L
The molarity of the concentrated HBr solution is 0.052 mol/L
Answer:
Percentage of yield = 1%
Explanation:
Given:
Amount of yield = 5g
Total amount of product = 500 gram
Find:
Percentage of yield = ?
Computation:
⇒ Percentage of yield = [Amount of yield / Total amount of product]100
⇒ Percentage of yield = [5g / 500g]100
⇒ Percentage of yield = [0.01]100
⇒ Percentage of yield = 1%

Answer:
36.75 grams of sulfuric acid will be required.
Explanation:
Moles of sodium hydroxide = 0.75 mol
According to reaction, 2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid ,then 0.75 moles of NaOH will :
sulfuric acid
Mass of 0.375 moles of sulfuric acid:
0.375 mol × 98 g/mol = 36.75 g
36.75 grams of sulfuric acid will be required.
