Okay your answer is 1 I think
Using the relationship M1V1 = M2V2 where M1 and M2 are the molar concentrations (mol/L or mmol/ml) and V1 and V2 are the volumes of the solutions, we can arrive at the following answer for the given problem:
<span>15.0M (L of stock solution) = 2.35M (0.25L) *all volumes were converted to liters.
L of stock solution = (2.35*0.25)/15.0
Therefore, 0.0392L or 39.17 ml of stock solution is needed. </span>
Answer:
The volume of the gas at given temperature is
Explanation:
= initial pressure of gas = 1 atm
= initial temperature of gas =
= initial volume of gas =
( , 1 mL = 0.001 L)
..[1]
= final pressure of gas = 2.1 atm
= final temperature of gas =
= final volume of gas = ?
..[2]
By dividing [1] and [2] we get combined gas equation :,
Now put all the given values in the above equation, we get:
The volume of the gas at given temperature is
Note that
1 m = 3.2808 ft
Therefore
1 km = 3280.8 ft
and
Answer: 1.0682 x 10⁵ ft/hr
Explanation:
(1). It is known that in a reaction equation, reactants are placed or written on left hand side and products are written on the right hand side.
For example,
Hence, in a reaction equation you start with the reactants and end up with the products.
(2). The number of atoms in a reaction will remain the same because according to the law of conservation of mass, mass of reactants will be equal to the mass of products.
Therefore, number of atoms on the reactant side will be equal to the number of atoms on product side.
