concentration
WE KNOW THAT
therefore
Now for conversion of mol to gram need the molar mass of element in which particular value convert to.
let us take
we know that molar mass of is 2 gram
therefore
let take other example, for
we know that molar mass of O_2 is 32 gram
therefore
Answer:
It will take 3 days for their bird feeders to contain the same amount of bird seed
Step-by-step explanation:
Let the number of days it will take their bird feeder to contain the amount of bird seed be x
For Edith, the amount of birdseeds that will be left after x days will be;
4 1/2 - 3/4(x)
= 9/2 - 3x/4
For June, the amount of birdseeds that will remain after x days will be;
3 - 1/4(x)
= 3 - x/4
Since after x days, the amount of birdseeds will be equal;
Mathematically;
9/2 - 3x/4 = 3 - x/4
Let’s work with decimals to make things easier;
4.5 - 0.75x = 3 - 0.25x
4.5 -3 = -0.25x + 0.75x
1.5 = 0.5x
x = 1.5/0.5
x = 3
3 x 7 because three, seven times is 21
