Answer:
Mass of oxygen that will be required to produce 6 mole of water is 96g .
Explanation:
Mass of oxygen = ?
Atomic mass of oxygen is =16g
Molecular mass of O₂= 32 g
Now, according to question statement we need to calculate oxygen needed to produce 6 mol of water .
In 1 mol of water ,there is O₂/2 is present or we can say that 1 oxygen atom is present .
We also know that ,
1 mol of water has = 1 mole of oxygen
Therefore ,
6 moles of water will have 6 moles of oxygen atom
Mass of 6 moles of oxygen atom can be calculated as :
Mole =given mass/atomic mass
6=X /16
X = 16 x 6
=96g

Answer:
n, the number of moles of gas is the same
Explanation:
PV = n RT if P and V and T and R are the same , the n must be the same
n = numer of moles
Answer:
if an atom gains an electron, the ion has negetive charge
Answer:
A , 210.3 g
Explanation:
Given data:
Number of moles of SiO₂ = 3.50 mol
Mass of SiO₂ = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of SiO₂ = 60.08 g/mol
by putting values,
3.50 mol = mass/60.08 g/mol
Mass = 3.50 mol × 60.08 g/mol
Mass = 210.3 g
