Answer:
2.5×10^-7mol/dm^3
Explanation:
Firstly convert the cm^3 to dm^3
200×1000=200000dm^3
Calculate the g/dm^3
2/200000=0.00001g/dm^3
To calculate mol/dm^3
Mol/dm^3=mass given\molar mass
=0.00001/40
=2.5×10^-7mol/dm^3
Answer:
The correct answer is : 44 dollars.
Explanation:
A quarter is one fourth of a dollar that is the reason it is known as quarter. A quarter is 25 cents or 0.25 dollar in value. If Matthew has 176 quarters in his jar than the value of the total coins would be:
1 quarter = 0.25 dollar
1 quarter = 1/4 dollar.
4 quarter = 1 dollar
then, 176 / 4 = x dollar
= 44 dollar
Thus, The correct answer is : 44 dollars.
