solution:
Let's assume that a unit of compound 1 is 100g and a unit of compound 2 is 100g... in other words, compound 1 will be 30.43g X and 69.57g Y, and compound 2 will be 63.64g X and 36g Y.
According to the given in your problem, we can also write the following two chemical equations:
X+2Y--> 2(compound 1)
2X+Y--> 2(compound 2)
using the 100g units above we can also write this as:
X+2Y--> 2(30.43g X) + 2(69.57g Y)
2X+Y--> 2(63.64g X) + 2(36g Y)
We add these two chemical equations together and get:
3X+3Y--> 2(30.43g+63.64g X) + 2(69.57g+36g Y)
This can be written more simply as:
3X+3Y--> 188.14g X + 211.14g Y
In other words, 3 volumes of X gives 188.14g of X, and 3 volumes of Y gives 211.14g of Y. Dividing one by 3 and you get 62.71g per volume X, and 70.38g per volume Y.
x: 62.71 g/mol.
Y: 70.38 g/mol.
Answer:
6x = 9
Step-by-step explanation:
4x-5y = 12
2x+5y = -3
Add the equations together
4x-5y = 12
2x+5y = -3
-------------------
6x + 0y = 9
6x = 9
P = 3(m - 5)

m is the number of quarters that marie has
Answer:
2nd Option: 2sec²Ѳ
Step-by-step explanation:
Please see the attached pictures for full solution.
Step-by-step explanation:
Let x = 0.3333333...
Then 10x = 3.3333333....
We have 9x = 3, so x = 3/9 or 1/3.
