Answer:
35.00 mL
Explanation:
Answer & Explanation:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
Answer:
45.45 ml of dimethyl sulfoxide
Explanation:
density of dimethyl sulfoxide is 1.10 g/10⁻³L which is 1.10 g/mL
now we devise the next reasoning:
If 1.10 g of dimethyl sulfoxide have a volume of 1 mL
Then 50 g of dimethyl sulfoxide have a volume of X mL
X = (50 × 1) / 1.10 = 45.45 ml of dimethyl sulfoxide
To calculate the volume of dimethyl sulfoxide needed, you must divide the mass by the density. With the given values, the resulting volume is approximately 45.45 L.
The subject of this question relates to the concept of density, which is directly related to mass and volume. We can apply the formula Density = Mass / Volume, hence Volume = Mass / Density. The mass provided in the question is 50.0 g and the density of dimethyl sulfoxide is given as 1.10 g×10^-3. Plugging in these values into the Volume equation gives us Volume = 50.0 g / 1.10 g×10^-3, which equals ~45,454.55 mL or approximately 45.45 L.

Answer:
125 ml of HCl
Explanation:
The molarity of the stock solution to determine how many milliliters would contain 1.5 moles of HCl. Since a concentration of 12.0 mol/L means that you get 12.0 moles of hydrochloric acid per liter of solution,
Concentration of required HCl (C1) = 1.0M
Volume of required HCL (V1) = 1500 ml
Concentration of stock HCl (C2) = 12M
Volume of stock HCL (V2) = ?
C1V1 = C2V2
V2 = C1V1/C2 = 1*1500/12 = 125 ml
