Answer:
53.4%
Explanation:
N₂ + 3H₂ → 2NH₃
Given that:
26.3 g of H₂ react with N₂ to produce 79.0 g of NH₃
Then:
The number of moles of H₂ = 26.3g of H₂ * (1 mol of H₂/ 2.02g of H₂)
= 13.05 mol of H₂
The number of moles of NH₃ = 13.05 mol of H₂ * ( 2mol of NH₃/ 3 mol of H₂)
= 8.697 mol of NH₃
The mass of NH₃ = 8.697 mol of NH₃ *( 17.04g of NH₃/ 1 mol of NH₃) = 148.1 g of NH₃
The percent yield = actual yield/ theoretical yield * 100%
The percent yield = ( 79.0 g/ 148.1 g )* 100%
The percent yield ≅ 53.4 %

crystallized by heating the salt solution
Salt solutions can be crystallized to give solid salts.
67,029 to three significant figures
0.15 to one significant figure
52.8005 to five significant figures
3.17497 to three significant figures
a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.
Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.
Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.
Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.
For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
Therefore, a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.

Step 1: Define
9.65 × 10²⁵ molecules H₂O (water)
Step 2: Identify Conversions
Avogadro's Number
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
Step 3: Convert
Step 4: Check
Follow sig fig rules and round. We are given 3 sig figs.
