Answer:
Concentration of solution B is
Explanation:
Solution A: Total volume of solution A = (9.00+1.00) mL = 10.00 mL
According to law of dilution,
where and are initial and final concentration respectively. and are initial and final volume respectively.
Here = , = 1.00 mL, = 10.00 mL
So, =
So, concentration of solution A =
Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL
Similarly as above, =
So, concentration of solution B =
Explanation:
Hope this helps:)
Answer:
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and
the value of x in
HxA is 3
Explanation:
75ml of a solutipn of 0.1moL l-1 NaOH neutralises 25ml of a solution of an acid. The formula of the acid is HxA and the concentration of the acid is 0.1mol l-1. What is the value of x?
the concentration of both the and the base are the same at 0.1M
the base...NaOH has 0.1 moles/L of OH ion
75 ml of 0.1M base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion
but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH
which means the formula for the acid must be H3A and the value of x in
HxA is 3
The average speed is zero if our frame of reference is the rotation of the Earth because the relative distance with respect to the earth is zero.
Average speed = 0.26 km/hr
total time = 316 minutes
distance = speed * time
= 8.3 * 5*1/30 = 8.3 *1/6
= 1.38 km
Average speed = total distance / total time
1.38 km / 5.27
= 0.26 km/hr
Distance is described to be the importance or length of displacement among positions. observe that the gap between two positions is not the same as the distance traveled between them. Distance traveled is the whole period of the path traveled among positions. Distance traveled isn't a vector.
There are three foremost styles of average: imply, median, and mode. each of these strategies works barely otherwise and frequently results in slightly distinct ordinary values. The suggest is the maximum usually used commonly. To get the mean cost, you add up all of the values and divide this general by means of the variety of values.
