What is the mass in grams of 3.2 moles of argon?
From the Periodic Table, Argon has an atomic weight of 39.948. One mole of any element is equal to its atomic weight in grams. So 1 mole of Ar = 39.948g of Ar. Using that equality, you do the following calculation to find the number of moles of Ar in 22g of Ar: 22g Ar X 1mol Ar/39.948g Ar = 0.55mol Ar
How do you prepare 0.4M Na2Co3?
To prepare 0.4M Na2CO3 solution, dissolve 15.6g of Na2CO3 in water and make up to 1 liter of solution. Make sure to use a balance to accurately measure the mass of Na2CO3 and a volumetric flask to prepare the final volume.
How many grams are in 2 moles of carbon dioxide?
Apply the equation moles -= mass(g) / Mr Algebraically rearrange mass(g) = Moles X Mr We have 2 moles Mr(CO2) = 44 ( 12 + (2 x 16) = 44) Hence substituting mass(g) = 2moles X 44 mass = 88 grams.
What technique is used to find the Mr is chemistry?
The technique used to find the molecular weight or molar mass of a compound in chemistry is called mass spectrometry. This method involves ionizing a sample and analyzing the mass-to-charge ratio of the ions produced, which can be used to determine the molecular weight.
What is percentage of nitrogen in ammonium sulphet?
Ar of N = 14g/mol Ar of H = 1g/mol Ar of S = 32.1g/mol Ar of O = 16g/mol Mr of (NH4)2SO4 = 2[14+4(1)]+32.1+4(16) = 132.1g/mol There are two nitrogen atoms in one molecule of (NH4)2SO4 Therefore the mass of nitrogen = 2(14) = 28g/mol of (NH4)2SO4 Percentage of mass composition of nitrogen = (28/132.1) x 100% = 21.2%
Equation for marginal revenue and average revenue?
Marginal revenue (MR) is the incremental revenue for the last quantity sold, while average revenue (AR) is the mean revenue for all quantity sold. Mathematically: MR=dTR(Q)/dQ, e.i. MR is the first derivative of the total revenue function TR(Q) with respect to Q; while AR=TR(Q)/Q, e.i. is total revenue divided by Q. An interesting property of MR and AR is that when AR is falling, MR is less than AR; when AR is rising, MR is greater than AR. MR and AR intersect where dAR(Q)/dQ=0.
Is Mr the same as Ar?
I doubt it, I don't know what Mr is..
Why in monopoly AR equals MR?
look at the instructions
WHY under perfect competition AR equals MR?
In a perfect competition, a firm can sell any amount of output at a given market price. It means firm's additional revenue(MR) from the sale of every additional unit of the commodity will be just equal to the market price (i.e. AR). Hence average revenue and marginal revenue become equal (AR=MR) and constant in that situation. Consequently the AR and MR curve will be same and would be horizontal or parallel to the x-axis.
Why MR curve is below AR curve?
on youtube, there are some great videos about economics by pjaholden
What does Mr Krabs value?
Money
How market power is measured?
depends on the size of the gap which is created by the AR/D curve and the MR curve.

Who create economic value?
Mr. Economic Value Who else?
What is gram molecular weight of cabon dioxide?
The molar mass of CO2 is Mr (C)=12.01 Mr (0)=16.00 Therefore, the molar mass is (12.01+(16.00x2) since there are 2 oxygen atoms then the molar mass will be doubled for oxygen therefore, Molar Mass=48.01 g/mol

Marginal revenue curve?
Explain why the marginal revenue(MR) is always less than the average revenue (AR)?
