How many moles are in 125g of Zn?
The molar mass of Zn is approximately 65.38 g/mol. To find the number of moles in 125g of Zn, divide the mass by the molar mass: 125g / 65.38 g/mol ≈ 1.91 moles.
How many moles of air are there in a 125 mL flask if the pressure is 739 torr and the temperature is 18C?
To find the number of moles of air in the flask, we need to use the ideal gas law equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. First, convert the volume to liters (125 mL = 0.125 L) and the temperature to Kelvin (18°C + 273 = 291 K). Then, calculate the number of moles: n = (PV) / (RT). Substituting the values, we get n = (739 torr * 0.125 L) / (0.0821 L atm/mol K * 291 K). Calculate to find the number of moles.
How many half-lives have elapsed to yield a sample with 125 atoms of C-14 and 375 atoms of N-14?
To determine the number of half-lives that have elapsed, we first find the total number of atoms in the sample, which is 500 (125 + 375). The starting atom would have been from 250 atoms of C-14. To find the number of half-lives elapsed, we divide the total number of atoms by the starting amount (500/250). This gives us 2 half-lives that have elapsed.
How many grams of carbon dioxide are needed to produce 125 grams of urea?
To produce 1 mole of urea, 1 mole of carbon dioxide is needed. The molar mass of urea is 60 grams/mol, and the molar mass of carbon dioxide is 44 grams/mol. Therefore, to produce 125 grams of urea, 125 grams/60 grams/mol = 2.08 moles of urea is needed. This means 2.08 moles of carbon dioxide is needed, which is 2.08 moles * 44 grams/mol = 91.52 grams of carbon dioxide needed.
How many grams of KCl are needed to prepare 125 mL of a 0.720 M KCl solution?
To calculate the amount of KCl needed, we first need to find the number of moles of KCl required using the formula: moles = Molarity x Volume (in L). Then, we convert moles to grams using the molar mass of KCl, which is 74.55 g/mol. Finally, we use the formula: grams = moles x molar mass to find that approximately 6.33 grams of KCl are needed to prepare 125 mL of a 0.720 M solution.
How many moles of nickel (Ni) are there in 125 g of Ni?
125 g nickel is equivalent to 2,13 moles.
How many moles are in 125g of Zn?
The molar mass of Zn is approximately 65.38 g/mol. To find the number of moles in 125g of Zn, divide the mass by the molar mass: 125g / 65.38 g/mol ≈ 1.91 moles.
How many nickels are in 125 dollars?
A nickel is 5 cents so there are 20 nickels in one dollar. 125 dollars would then be 20 * 125 = 2500 nickels.

What is 125 gof HSO in moles form?
No such thing as HSO in chemistry. If you're referring to H2SO4, which is sulfuric acid, then 125 grams of it would be: H2SO4 = 98g/mol; 98/1=125/x; solve for x to get about 1.28 moles.
How many quarters makes 25 nickels?
A nickel is 5 cents so 25 nickels is 25*5 = 125 cents. A quarter is 25 cents so 125 cents = 125/25 = 5 coins.
How many atoms are in 125 grams of Calcium?
Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
What does 125 stamped on silver mean?
.125 means it is nickel. The stamp means what percentage of silver the piece has. So .125 is 12.5% silver, and the rest is other metals
What does the silver hallmark 125 stand for?
.125 = 12.5% so, in essence mainly not silver - likely to be nickel amongst other base metals
How many moles of pottasium are in 125g of KCl?
The formula given shows that each formula unit of KCl contains one atom of potassium. Therefore, the number of moles of potassium will be the same as the number of moles of KCl, and its gram formula mass is 74.55. therefore, the number of moles is 125/74.55 or 1.68, to the justified number of significant digits.

How many moles are in 125.00 grams of sodium sulfide?
There are at least three kinds of sodium sulfide, but assuming that the question refers to the most common one with the formula Na2S, its gram formula mass, the mass corresponding to molar mass for covalently bonded compounds, is 78.04. Therefore 125.00 constitutes 125.00/78.04 or 1.6017 "moles".
