45.6 mL of 0.0600 M of is added to 25.0 mL of HCl of unknown concentration then , the concentration of HCl is 0.032 M .
Calculation ,
Formula used : =
...( 1 )
Where = concentration of
= 0.0600 M ( given )
= concentration of HCl = ? ( to be find )
= volume of
= 25.0 mL ( given )
= volume of HCl = 45.6 mL ( given )
Now , put the value of all volume and concentration in equation ( 1 ) we get .
0.0600 M × 25.0 mL = × 45.6 mL
= 0.0600 M × 25.0 mL / 45.6 mL = 0.032 M
Therefore , concentration of unknown concentration of HCl is 0.032 M .

<u>Answer:</u> The weight of water bed in pounds is 1850.16 lb
<u>Explanation:</u>
To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 210 cm
b = breadth of cuboid = 160 cm
h = height of cuboid = 25 cm
Putting values in above equation, we get:
(Conversion factor:
)
To calculate the mass of waterbed, we use the equation:
Density of waterbed =
Volume of waterbed =
Putting values in above equation, we get:
Hence, the weight of water bed in pounds is 1850.16 lb
