How much methanol needed to make 10 ppm calibration gas in 100ml nitrogen?
To prepare a 10 ppm (parts per million) calibration gas in 100 mL of nitrogen, you need to calculate the amount of methanol required. Since 10 ppm means 10 mg of methanol per liter of gas, for 100 mL (0.1 L), you would need 1 mg of methanol. To achieve this, you can directly weigh out 1 mg of methanol and dilute it in the 100 mL of nitrogen.
Methanol has a density of 0.79 what would the mass of 589mL of methanol be?
To solve this question you need to use the formula, density = mass/volume. So the equation would be 0.79 = mass/589mL. The answer is 465g.
What is the percent by volume of 25 ml of methanol in 75 ml of water?
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
Mass of ten ml of water?
The mass of 10 mL of water is 10 g.
How much methanol needed to make 100 ppm solution in 100ml water?
To make a 100 ppm solution of methanol in 100 mL of water, you would need 10 mg of methanol. This is because 100 ppm is equivalent to 100 mg/L, and since you have 100 mL of water, you would need 10 mg of methanol (100 mg/L x 0.1 L).
The molar enthalpy of vaporization of methanol is 38.0kjmol at 25c how much heat energy is transfer is required to convert 250.0 ml of the alcohol from liquid to vapor the density of CH3OH .787gml?
In order to determine the amount of heat energy required, you first need to calculate the mass of 250.0 ml of methanol using the density provided (ρ = 0.787 g/ml). Mass = Volume x Density. Once you have the mass, you can use the molar enthalpy of vaporization value to determine the heat energy required using the formula: Heat energy = mass (in mol) x molar enthalpy of vaporization.
What is the final percent concentration of the solution when 600 ml of 100 percent methanol added to 4400 ml of water?
The final percent concentration of the solution would be approximately 12.0% methanol. This is calculated by dividing the volume of methanol by the total volume of the solution (600 ml / 5000 ml) and then multiplying by 100 to get the percentage.
How much does 1 ml of methanol weigh?
Methanol, CH4O, has a molar mass of 32g (12g+4.0g+16g)* *note this is only rounded to two sig figs, since the mass of elements are usually rounded to the tenths place. Next, simply use dimensional analysis: 1ml/22.4L X 32g. you should get the right answer by doing the steps shown above.
What is the destiny of an object with the mass of 10 grams and volume of 2.0 ml?
Density = mass/milliliters Density = 10 grams/2 ml = 5 g/ml ---------------
How many ml is 230 grams?
The number of milliliters to have a mass of 238 g depends upon the mass density of the substance. For pure water at 4.0 C : ----------------------------------- d = 1.000 g per mL d = m / V ..... [ By Definition of mass density ] V = m / d = ( 238 g ) / ( 1.000 g /mL ) = 238 mL <------- For methanol at 10 C : --------------------------- d = 0.801 g / mL V = m / d = ( 238 g ) / ( 0.801 g / mL ) = 297 mL <-----------
What is the percent volume of 25 mL of methanol in 75 mL of water?
25%
How do you find the density of a mL liquid that has a mass of 1o grams?
Density is calculated by dividing the mass of a substance by its volume. In this case, if the mass of the liquid is 10 grams and it occupies a volume of 1 mL, the density would be 10 grams per 1 mL, or simply 10 g/mL.
