Each choice refers to the same solute and solvent. A) 2.4 g solute in 2 mL solution. B) 2.4 g solute in 5 mL solution. C) 20 g solute in 50 mL solution. D) 30 g solute in 150 mL solution. E) 50 g solute in 175 mL solution. chemistry. X. (b) 0.87 M \ce {NaOH} NaOH solution (density of solution = 1.04 g/mL),
How many grams of CO2 would be produced if 350.0 mL of diethyl ether were combusted in an unlimited amount of oxygen ? Density of diethyl ether is 0.713g/mL. C4H10O + O2 ---> H2O + CO2 Thanks for all your content!
To make a liter of dilution with a solution ratio of 1:5, you'll need to mix 167 ml of stock solution in 833 ml of water. To get these amounts: Use the volume of solute formula and substitute the known quantities: solute_volume = final_volume / (solvent_ratio + solute_ratio) solute_volume = 1 l / (5 + 1) solute_volume = 0.167 l = 167 ml 0.235 moles/L x 0.25 L = 0.05875 moles KCl needed to make 250 ml Now, to convert that to grams needed 0.05875 moles KCl x 74.55 g/mole = 4.38 grams KCl needed (to 3 significant figures)
The density of water actually varies depending on conditions (cold water is denser; warm water is less dense), but the value typically used in calculations is 1.00 gram per milliliter (1 g/mL). In other words, 1 milliliter of water has a mass of 1 gram. A drop of water is 0.05 mL of water, so its mass would be 0.05 grams.

Grams of water to US cups; 110 grams of water = 0.465 US cup: 120 grams of water = 0.507 US cup: 130 grams of water = 0.549 US cup: 140 grams of water = 0.592 US cup: 150 grams of water = 0.634 US cup: 160 grams of water = 0.676 US cup: 170 grams of water = 0.719 US cup: 180 grams of water = 0.761 US cup: 190 grams of water = 0.803 US cup: 200
The ratio strength is 1 in 2000w/v. What is the percentage strength and the amount concentration expressed as mg/mL? By convention, a ratio strength 1:2,000 w/v means 1g in 2,000mL. The percentage strength is the number of grams of ingredient in 100mL of product. Let the percentage strength be p and the amount of solid in grams in 1mL of product be PnDExey.
