No of moles = given mass ÷ molecular mass
n = 55.98 ÷ (12+19×2+35.5×2)
Answer:
empirical formula = C3H7
molecular formula = C6H14
AMSWER :
CHEMICAL FORMULA :
• WATER - H2O
• CARBONDIOXIDE - CO2
• SODIUM HYDROXIDE - NaOH
• SULPHURIC ACID - H2SO4
• SODIUM CHLORIDE - NaCI
• SODIUM BICARBONATE - NaCHO3
Pressure given by:
Pressure=(force)/(area)
Force=Mass*gravitational pull
Mass=34Kg
gravity=9.80
so,
force=34*9.8=333.2
thus;
pressure=333.2/25=13.328=13.3 N/cm^2
Hope this helped :)
Answer:
vigorous
Explanation:
