La cantidad de azúcar en la solución es 239.4 gramos. En este caso, el azúcar es el soluto, y el agua el solvente.
El azúcar es el soluto el cual se encuentra disuelto en una solución acuosa que posee una masa de 6.3 kilogramos.
Un kilogramo equivale a 1,000 gramos. Es decir, 1 Kilogramo (kg) = 1,000 gramos (gr).
Entonces, la cantidad de azúcar puede ser calculada utilizando la regla de tres simple >>
6,300 gr ________ 100 %
X ______________ 3.8 %
X = (3.8 x 6,300)/ 100 = 239.4 gr

It's B: there are 2 <span>HCl molecules are needed to fulfill the conservation of mass.</span>
The formula mass is 132.14 g/mol
Answer:
The key to chemistry is to change everything to moles. Then when you have the answer in moles change the answer back to grams, liters, or whatever you want.
change 25 grams of potassium chlorate to moles.
calculate the gram molecular mass of potassium chlorate.
Chlorate is Cl with 3 oxygens. ate = saturated. Chlorine has seven valance electrons when it is saturated six of these electrons are used by oxygen ( 2 electrons per oxygen) leaving only 1 electron.
1 K x 39 grams/mole
+1 Cl x 35.4 grams/ mole
+3 O x 16 grams/ mole
= 122.4 grams / mole Potassium Chlorate
25
122.4
= moles.
2.05 moles of Potassium Chlorate.
There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride.
2.05 moles of Potassium Chlorate will produce 2.05 moles of Potassium Chloride.
Find the gram molecular mass of Potassium Chloride.
1 K x 39 = 39
+1 Cl x 35.4 = 35.4
= 74.4 grams / mole.
2.05 moles x 74.4 grams/ mole = 15.2 grams
