Answer:
139.11 grams
Explanation:
The molarity (M) is equal to m (moles) /L (liters).
Notice how it is in mL so converting it would be 0.75 L (750*10-3)
Now plug in the information
1.75=m/0.75
m=1.3125
Now m is in moles so convert to grams to get the mass
1.3125 mol Na2CO3 * 105.9888 g Na2CO3 = 139.1103
Answer:
The mass percentage of chlorine is 60.66 % chlorine in the compound sodium chloride.
Explanation:
It will be great if you searched on the internet then just questioning it on here because on here it takes a bit to get that so might as well google it
2C4H10 + 13O2 -> 8CO2 + 10H2O
Answer:
V = 56.72 L
Explanation:
Given data:
Number of mole of neon gas = 0.83 mol
Temperature = 35°C
Pressure = 0.37 atm
Volume of gas = ?
Solution;
Temperature = 35°C (35+273 =308K)
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
Now we will put the values in formula.
V = nRT/P
V = 0.83 mol ×0.0821 atm.L/mol.K ×308K / 0.37 atm
V = 20.99 L/ 0.37
V = 56.72 L
