Ilya [14]3 years ago
8 0

Answer:

100 cal

Explanation:

Given data:

Mass of carbohydrate = 19 g

Mass of protein = 1 g

Mass of fats = 4 g

Solution:

The average calories content of

Protein 4 cal/g

Carbohydrate 4 cal/g

Fat 9 cal/g

Then,

1 g protein × 4 cal/g =  4 cal

4 g fat × 9 cal/g = 36 cal

19 g carb. × 4 cal/g = 76 cal

               Total calories = 116 cal  

Round to one significant figure = 100 cal

How many moles of MgCl2 are there in 319 g of the compound?
Leokris [45]

Hey there!:

Molar mass MgCl2 = 95.2110 g/mol

So:

1 mole MgCl2 -------------- 95.2110 g

moles MgCl2 ---------------- 319 g

moles MgCl2 = 319 * 1 / 95.2110

moles MgCl2 = 319 / 95.2110

=> 3.350 moles of MgCl2


Hope that helps!

When 33 g of CaO and 10 g of H2O react, how many grams of calcium hydroxide would you expect to be produced* Explain your answer
MrMuchimi

Answer:

41.44 g

Explanation:

First of all, we must put down the equation of the reaction;

CaO + H2O ----->Ca(OH)2

Number of moles of CaO = 33g/56 g/mol = 0.59 moles

Number of moles of H20 = 10g/18 g/mol = 0.56 moles

Since the reaction is in 1:1 mole ration, H2O is the limiting reactant

Hence;

mass of Ca(OH)2 produced = 0.56 moles * 74 g/mol = 41.44 g
