Explanation:
Ans: 15.1 grams
Given reaction:
Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3
Mass of Na2CO3 = 20.0 g
Molar mass of Na2CO3 = 105.985 g/mol
# moles of Na2CO3 = 20/105.985 = 0.1887 moles
Based on the reaction stoichiometry: 1 mole of Na2CO3 produces 2 moles of NaOH
# moles of NaOH produced = 0.1887*2 = 0.3774 moles
Molar mass of NaOH = 22.989 + 15.999 + 1.008 = 39.996 g/mol
Mass of NaOH produced = 0.3774*39.996 = 15.09 grams
There are 1000 mililiters in a liter, so 1000 ml for every liter, you have 5 liters, so:
5L*1000 = 5000 mL
DescriptionThe dhalang or dalang is the puppeteer in an Indonesian wayang performance. In a performance of wayang kulit, the dalang sits behind a screen made of white cotton stretched on a wooden frame. Above his head, hanging from beams attached to the top of the screen, is the lamp, which projects the shadows onto the screen
Yes the kingdom is more specific
M/V=D
65.14/35.4≈1.84
The density of the sulfuric acid would be about 1.84g/mL
