If you add water to a 15.00 mL solution of 3.22 M CaCl2 (MM=110.98 g/mol) in order to create a solution that is 15.00% CaCl2 by

mass, what is the final mass of the new solution. The density of water is exactly 1.00 g/mL. Assume that the density of the CaCl2 solution is also exactly 1.00 g/mL.

The mass of the new solution is 35.7 g.  

Step 1. Calculate the <em>moles of CaCl₂</em> in the first solution.  

[\text{Moles of CaCl}_{2} = \text{0.015 00 L solution} \times \frac{\text{3.22 mol CaCl}_{2}}{\text{1 L solution }} = \text{0.048 30 mol CaCl}_{2}\\  

Step 2. Calculate the <em>mass of CaCl₂</em>.  

\text{Mass of CaCl}_{2} = \text{0.048 30 mol CaCl}_{2} \times \frac{\text{110.98 g CaCl}_{2} }{\text{1 mol CaCl}_{2} } = \text{5.360 g CaCl}_{2} \\  

Step 3. Calculate the mass of the new solution.


\text{Mass of solution }= \text{5.360 g CaCl}_{2} \times \frac{\text{100 g solution }}{\text{15.00 g CaCl}_{2} } = \textbf{35.7 g solution} \\

Answer:

7.5 g of hydrogen gas reacts with 50.0 g oxygen gas to form 57.5 g of water.

Explanation:

Here we have the check if the mass of the reactants is equal to the mass of the products.

Reactants

7.5+50=57.5\ \text{g}

Products

57.5\ \text{g}

The data is consistent with the law of conservation of matter.

Reactants

50+243=293\ \text{g}

Products

206+97=303\ \text{g}

The data is not consistent with the law of conservation of matter.

Reactant

17.7+34.7=52.4\ \text{g}

Products

62.4\ \text{g}

The data is not consistent with the law of conservation of matter.

Only the first data is consistent with the law of conservation of matter.

Cuántos mililitros de agua hay en 3 litros de una botella de naranjas y las solucion tiene una concentracion de 20% v/v
sertanlavr [38]

Respuesta:

2400 mL

Explicación:

Paso 1: Información dada

  • Volumen de solución: 3 L (3000 mL)
  • Concentración de naranja: 20 % v/v

Paso 2: Calcular el volumen de naranja

La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.

3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja

Paso 3: Calcular el volumn de agua

El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.

VSolución = VNaranja + VAgua

VAgua = VSolución - VNaranja

VAgua = 3000 mL - 600 mL = 2400 mL
