How many moles are there in 37 grams of calcium hydroxide?
Use the equationmol = mass / RFM (or RAM)mol = 37 / (40 + 16x2 + 1x2)mol = 37 / 74mol = 0.5
What is formula mass of steel?
The RFM of steel varies dependent upon the levels of differing impurities which give each specific type of steel its desired properties. You need to be more specific in you question. Which type of steel?
What mass of sodium chloride is formed when 30ml of a 0.0250 M sodium phosphate solution is mixed with an appropriate amount of potassium chloride?
The equation for the reaction: Na3PO4 + 3KCl ---> 3NaCl + K3PO4 Shows that 1 mol of sodium phoshpate will yield 3 mol of sodium chloride. The number of moles of Na3PO4 present in the solution in this reaction = concentration x volume => 0.0250 mol.dm-3 x 0.03 dm3 = 0.00075 mol. When reacted with excess KCl, this will give 0.00075 mol x 3 = 0.00225 mol of NaCl. The mass of NaCl formed = mol x RFM => 0.00225 x 58.5 = 0.132 g
How many moles are in 9.8 grams of Calcium?
Strictly, elements such as calcium do not have "moles", but the corresponding term, for Avogadro's Number of atoms of an element, is called "gram atomic mass". For calcium, this number is about 40.08 grams. Therefore, 9.8 grams of calcium is about 9.8/40.08 or 0.24 gram atoms, to the justified number of significant digits.
What is the RFM of H20?
18
How do you assess Recency Frequency and Monetary Value RFM?
Via test versus target groups. You need to analyze the responses by RFM quintile. Check out this whitepaper on RFM (see related link area below). Jim
What types of companies would need to use RFM methods?
RFM is a method used for evaluate customer behavior and defining market segments. The type of companies that would need to use the RFM method are the companies that have customers like retail companies.

What is the running pressure of car airconditioning suction and discharge pressure using 134a refrigerant when operating?
35suction pressure in 1000 rfm
How many moles of manganese are contained in 0 point 1 moles of hydrated manganese II sulphate MnSO4 4H2O which has an RFM of 223?
I must have the same sheet as you as I have the exact same question. Okay, The RFM of Manganese (Mn) is 54.9 The RFM of MnSO4 4H20 is 223 The percentage of Mn in MnSO4 4H2O is 54.9/223 X 100 and that is 24.6 % 0.1 Moles of MnSO4 4H20 is 223/100 X10 = 22.3 24.6 % (percentage of Mn in MnSO4 4H2O) of 22.3 (0.1 Moles of MnSO4 4H2O) is 5.49g Then you do 5.49g/54.9g (RFM of Mn) which is 0.1 Moles of Mn, which is your answer.
What does it mean when a property goes from RFM to For sale?
Usually it means a rear-ended financed mortgage where you pay the fee's at end of term ( rearend )
What are the names of the first five carboxylic acids?

What are the advantegs of collimation method?
"The collimation method is the height-of-instrument method of leveling whereby fore-and-aft readings are made on a leveling staff by an instrument placed intermediately so that the rise or fall between the fore station and the back station is shown by a change in the staff reading." "The difference between Height of Collimation Method (HCM) and Rise and Fall Method (RFM) are as follows: HCM :It is more rapid and saves a considerable time and labour. RFM : It is laborious as the staff reading of each station is compared to get a rise or fall. HCM : It is well adopted for reduction of levels for construction work such as longitudinal or cross-section levelling operations. RFM : It is well adopted for determining the difference in levels of two points where precision is required. HCM : There is no check on reduction of R.L. of intermediate stations. RFM : There is a complete check on the reduction of RL of the intermediate stations. HCM : There are only two arithmetical checks i.e. the difference between the sum of the fore sights must be equal to be the difference in R.L. of the last station and first station. RFM : There are three arithmetical checks i.e the difference between the sum of the back sights and the sum of fore sights must be equal to the difference between the sum of the rises and the sum of the falls as well as it must also be equal to the difference in RL of the last station and first station. HCM : Errors if any in intermediate sights are not detected. RFM : Errors in intermediate sights are noticed as these are used for finding out rises and falls.

What is the mass number of NaCl?
The mass of sodium (Na) is 23g and the mass of Chlorine (Cl) is 35g, the total mass of NaCl is 58g. We know this by adding the atomic mass together giving us the RFM.
