How many moles of hydrogen atoms are contained in 3 moles of ammonia?
Since ammonia has a chemical formula of NH3, it contains one mole of nitrogen and three moles of hydrogen per mole of ammonia. Therefore, 3 moles of ammonia contain 3 moles of nitrogen and 9 moles of hydrogen atoms.
How many grams are there in 3 moles of CuSO4?
The molar mass of CuSO4 is 159.6 g/mol. To find the mass of 3 moles of CuSO4, multiply the molar mass by the number of moles: 3 moles * 159.6 g/mol = 478.8 grams. Therefore, there are 478.8 grams in 3 moles of CuSO4.
How do you find if you have 14.5 moles of N2 how many moles of H2 are theoretically needed to produce 22.5 moles of NH3 according to the reaction N2 plus 3H2 2NH3?
N2 + 3H2 -> 2NH3 If you have moles produced you can do it this way. 22.5 moles NH3 (3 moles H2/2 moles NH3) = 33.8 moles H2 needed -----------------------------------
How many moles of sulfate ions (SO42) are present in 1.7 moles of Al2(SO4)3?
There are 3 moles of sulfate ions (SO4^2-) present in 1 mole of Al2(SO4)3. Therefore, in 1.7 moles of Al2(SO4)3, there would be 3 * 1.7 = 5.1 moles of sulfate ions.
How many moles of potassium hydroxide are needed to neutralize 3 moles of nitric acid?
The balanced chemical equation for the reaction between potassium hydroxide (KOH) and nitric acid (HNO3) is 1:1 ratio. Therefore, 3 moles of nitric acid will require 3 moles of potassium hydroxide to neutralize it.
there are 3 blue marbles 7 green marbles 5 swirled marbles in a circle what fraction of the marbles are blue?
The fraction is 3/15.
What makes Marbles so much fun?
Playing marbles is so much fun when you accumulate many marbles. There is little, or no fun, when you lose your marbles!
The ratio of white to red marbles in a bag is 3 to 4.Which is trueFor every 3 white marbles, there are 7 red marbles. There could be 6 white marbles and 12 red marbles. There could be 12 white marbles and 16 red marbles?
There could be 12 white marbles and 16 red marbles
A sack contains red and blue marbles. The ratio of red marbles to blue marbles is 43. If there are 16 red marbles in the sack how many blue marbles are in the sack?
Given the ratio of red marbles to blue marbles is 4:3 and there are 16 red marbles, we can set up a proportion. If 4 parts represent 16 red marbles, then 1 part equals 4 marbles (16 ÷ 4). Thus, for the blue marbles, which represent 3 parts, there are 3 × 4 = 12 blue marbles in the sack.
Jerry has a total of 23 marbles The marbles are either blue or green He has three more blue marbles than green marbles How many green marbles?
Let X = the number of green marbles. X+3 = the number of blue marbles. X + (X+3) = 23 2X + 3 = 23 2X = 20 X = 10 or the number of green marbles.
2 out of 3 of John's marbles is equal to 3 out of 5 of Max's marblesThey have 266 marbles altogether How many marbles does John have?
2 out of 3 times 3 out of 5
Jerry has a total of 23 marbles the marbles are either blue or green he has three more blue marbles than green marbles how many green marbles does he have?
a+b=23 b=a+3 a+b a+(a+3)=23 a+a=23-3 2a=20 a=10 green marbles=10 blue marbles =23-10 =13
John has 22 marbles. He has twice as many red marbles as green marbles. The rest of his marbles are yellow. How many yellow marbles does John have?
He has a number of yellow marbles that leaves a reminder of 2 when divided by 3 and is a number smaller than 22. That is the number of yellow marbles = 2(mod 3).
In a bag are three red marbles and green marbles if two marbles are drawn from the bag at the same time what is the probability that both marbles will be red?
To find the probability of drawing two red marbles from a bag containing three red marbles and two green marbles (a total of five marbles), you can use the combination formula. The number of ways to choose 2 red marbles from 3 is ( \binom{3}{2} = 3 ), and the total ways to choose 2 marbles from 5 is ( \binom{5}{2} = 10 ). Thus, the probability of drawing two red marbles is ( \frac{3}{10} ) or 0.3.
What is the number of each colour of marbles in a bag of 76 marbles if the ratio of red marbles to green marbles is 2 to 3 and the ratio of green marbles to blue marbles is 9 to 4?
The ratios are: red : green = 2 : 3 = (2×3) : (3×3) = 6 : 9 green : blue = 9 : 4 → ratio of red : green : blue = 6 : 9 : 4 There are 6 + 9 + 4 = 19 parts 76 marbles ÷ 19 parts = 4 marbles per part → red: 6 parts = 6 × 4 marbles per part = 24 red marbles → green: 9 parts = 9 × 4 marbles per part = 36 green marbles → blue: 4 parts = 4 × 4 marbles per part = 16 blue marbles To check: red + green + blue = 24 marbles + 36 marbles + 16 marbles = 76 marbles in the bag.
