How many moles of gas does a steel cylinder witha volume of 45 liters contain at standard temp pressure?
stp= 22.4 dm3, 1L = 1 dm3 1mole ---> 22.4dm3 xmole ---> 45dm3 45/22.4 = 2.001 moles
What is 2.5 grams per 100 milliliters in moles per Liter?
To convert grams per milliliter to moles per liter, you need to know the molar mass of the substance. Assuming the substance is water (H2O), its molar mass is 18.015 g/mol. Therefore, 2.5 grams per 100 milliliters is equivalent to approximately 138.6 mmol/L (millimoles per liter) for water.
How many liter in a meter?
Completely depends on the volume of the container.
How many ml equal 1l?
there are 1000mL in 1L
How many moles of sucrose are there in 5 liters of sugar that has a concentration of 0.5 M?
Is that 0.5L ? If yes, as 1L=1dm3, no. of mole= (volume)(concentration)=(0.5)(2)=1 mol
How many moles of gas does a steel cylinder witha volume of 45 liters contain at standard temp pressure?
stp= 22.4 dm3, 1L = 1 dm3 1mole ---> 22.4dm3 xmole ---> 45dm3 45/22.4 = 2.001 moles
How do you convert moles to Litters?
number of moles = Volume (l) . Conc (mol-1l) so V = C/N
How many moles of each ion are found in a 1L of 5m of MgSo4 solution?
Molarity = moles of solute/Liters of solution5 M MgSO4 = moles MgSO4/1 L5 moles MgSO4=============since all is one to one in ion countMg 2+ = 5 moles--------------------------andSO4 2- = 5 moles----------------------
How many liters in a milk container?
In Australia, there are several different sizes. The most popular being 600mL, 1L, 2L and 3L.
What is 2.5 grams per 100 milliliters in moles per Liter?
To convert grams per milliliter to moles per liter, you need to know the molar mass of the substance. Assuming the substance is water (H2O), its molar mass is 18.015 g/mol. Therefore, 2.5 grams per 100 milliliters is equivalent to approximately 138.6 mmol/L (millimoles per liter) for water.
How many ml of 0.25M KCl are needed to provide 0.012 moles of KCl?
To find the volume of 0.25M KCl needed to provide 0.012 moles of KCl, you can use the formula: moles = Molarity x Volume (in liters). Rearranging this formula to solve for Volume gives Volume = moles / Molarity. Plugging in the values, Volume = 0.012 moles / 0.25 mol/L = 0.048 L = 48 ml.
How many molecules are present in 2.5 moles of SO2?
M means molarity, with units moles/Liter. Using this information, we use dimensional analysis: 2.5mL x (1L/1000mL) x (9mol/1L) = 0.0225mol
Calculate the volume of solution needed to dissolve 0.25 moles NaCl to make a 3.0M solution?
3.00 M, or 3 moles per (L) "liter" calls for having 3 moles per liter of the solution. The question asks how many moles must be in 250ml of a solution that has 3 moles per Liter. You must ask yourself what percent of 1 Liter is 250mls? Since there are a thousand ml in one liter, (1000ml=1L), then 250ml is exactly 25% of a Liter, or .25L. So, 250ml can only hold 25% of the 3.00 Molarity. Meaning that you multiply 3 x .25 and get .75 moles.
What is the pressure on a 1.0 L sample that contains 1.5 g of gas?
If the gas in question was air (I assume gas does not mean gasoline in this case) there would be 1.225g/dm3 at sea level with a pressure of 1013.25 millibars and a temperature of 150C. The container in this case is 1L which is equal to 1dm3 in volume and 1.5g of air will give the container a pressure of 1013.25x1.5/1.225 The result is 1240.71mb. Claudiosanto
How many moles of NaCl is required to make 1L of a 140mM solution?
To find the moles of NaCl needed, first convert 140 mM to M by dividing by 1000. Then, use the formula moles = Molarity x Volume (in liters) to calculate the moles required. In this case, the calculation would be: 0.140 mol/L x 1 L = 0.140 moles of NaCl.
If you have a fishtank that holds 5 liters of water and you fill it using 1000 ml how many times will it take to fill container?
1000 ml = 1l 1*5=5 It will take 5 times to fill the container.
