How many liters of a 5.0 percent glucose solution would you need to obtain 75 g of glucose?
To calculate the amount of glucose in the solution, use the formula: mass = volume × concentration Rearrange the formula to solve for volume: volume = mass / concentration Substitute the values to find: volume = 75 g / 0.05 = 1500 mL = 1.5 L Therefore, you would need 1.5 liters of the 5.0% glucose solution to obtain 75 g of glucose.
What is the percent concentration when 30gms of codeine is dissolved in 2 liters of solution?
The percent concentration of the codeine solution is 1.5%. This is calculated by dividing the mass of codeine (30g) by the total mass of the solution (2000g, since 1 liter of water is approximately 1000g) and then multiplying by 100.
33 percent of 2 gallons is how many liters?
33 percent of 2 gallons is equivalent to 0.66 gallon. When converted to liters, 0.66 gallon is approximately equal to 2.49 liters.
How do you find the concentration of 3.50g of potassium chromate in 100 ml water?
K2CrO4 Molarity (concentration) = moles of solute/Liters of solution (100 ml = 0.100 Liters ) Find moles K2CrO4 first. 3.50 grams = (1 mole K2CrO4/194.2 grams) = 0.01802 moles K2CrO4 ----------------------------------------------next Molarity = 0.01802 moles K2CrO4/0.100 Liters = 0.180 M K2CrO4 -------------------------
4.32 x 102 moles of CH3COOH in 20.0 liters of water?
This is a calculation of the concentration of acetic acid (CH3COOH). To find the concentration, you divide the moles of CH3COOH by the volume of water in liters. So, the concentration would be 4.32 x 10^2 moles / 20.0 liters = 21.6 moles/liter.
What is 50 percent of a 3 liter?
Fifty percent of 3 liters is 1.5 liters. To calculate this, you simply multiply 3 liters by 0.50 (or 50%). Therefore, 50% of 3 liters equals 1.5 liters.
How much water must be added to 300 liters of a solution so that its concentration change from 25 percent to 20 percent?
Well, isn't that a lovely little problem to solve? To decrease the concentration from 25% to 20%, we need to dilute the solution. Since the concentration is decreasing by 5%, we can calculate that we need to add 60 liters of water to the 300 liters of solution to achieve the desired concentration of 20%. Just like painting, a little change can make a big difference in creating the perfect mixture.
What is the process to calculate the molarity of a solution?
To calculate the molarity of a solution, you need to divide the moles of solute by the volume of the solution in liters. The formula for molarity is M moles of solute / liters of solution. This will give you the concentration of the solution in moles per liter.
How do you calculate moles from molarity?
To calculate moles from molarity, you use the formula: moles = molarity x volume (in liters). Simply multiply the molarity of the solution by the volume of the solution in liters to find the number of moles present in the solution.
How do you find the concenration of a solution?
Concentration of a solution is recorded in molarity (M). Molarity is the moles of solute divided my liters of solution. So to find the concentration of a solution, calculate the number of moles of the solute (the chemical being dissolved) and measure the number of liters of the solution (the water), then divide them.
If the concentration of gasoline in 650000 liters of water is 3 ppm how many liters of gasoline are in the water?
There are 1950 liters of gasoline in the 650000 liters of water. This is calculated by multiplying the concentration of 3 ppm by the volume of water in liters.
The concentration of 58.5 g of NaCl in 2 L of solution?
The concentration of 58.5 g of NaCl in 2 L of solution is 29.25 g/L. To calculate the concentration, divide the mass of the solute (NaCl) by the volume of the solution (in liters).
What is 0.5 percent of 75 liters?
0.5 percent of 75 liters is 0.375l.
What is the molarity of a solution with a percent concentration of a given solute?
To find the molarity of a solution with a percent concentration of a solute, you need to know the molecular weight of the solute and the density of the solution. Then, you can use the formula: Molarity (percent concentration density) / (molecular weight 100).
How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
What is 10 percent of 2 liters?
200 milliliters
