It depends on the grade
no 70 percent of all oxygen comes from algee and 100 percent of plants are decendant of algee
To determine the mass percent of oxygen in a compound, you would calculate the mass of oxygen in the compound and then divide it by the total mass of the compound, before multiplying by 100. The formula is: (mass of oxygen in compound / total mass of compound) x 100%.
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.
(16.0g + 16.0g)/(32.1g + 16.0g + 16.0g) x 100 %
yes
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
The percent composition of oxygen in BeO is approximately 89.7%. This can be calculated by dividing the molar mass of oxygen by the molar mass of BeO and multiplying by 100.
100% helium
No!It's so not worthy to spend such precious money on 100% pure oxygen!Ha!Ha!
The percent of oxygen in KClO3 is 48.4%. This can be calculated by dividing the molar mass of oxygen in KClO3 (48 g/mol) by the molar mass of KClO3 (122.55 g/mol) and multiplying by 100%.
The percent composition of oxygen in Al(OH)3 (aluminum hydroxide) is 35.77%. This is calculated by dividing the molar mass of oxygen by the molar mass of the compound and multiplying by 100.
