Answer:

45g

Explanation:

first we will find out which is the limiting reactant (hope you know how to find it)

Cao is the limiting reactant

so

we will find the number of moles of cao which is 0.45 mol

as according to the equation cao and caco3 have ratios 1:1 so both will have the same no. of moles

then by multiplying 0.45mol by 100 (mr of caco3) we will get the mass of caco3 which is 45g

1718 l of a 0.3556-m c3h7oh solution is diluted to a concentration of 0.1222 m, what is the volume of the resulting solution
Agata [3.3K]
Answer : The volume of the resulting solution will be 0.4999 L.

Explanation : As the two molar concentration of the C_{3} H_{7}OH solution are given and one of the volume concentration needs to be found.

So, according to the formula :-  m_{1}V_{1} = m_{2}V_{2}

And here if we consider V_{1} as 0.1718 L moles and m_{1}  as 0.3556 moles then we need to find V_{2} as m_{2}  is given as 0.1222 moles.
Hence on solving the formula we get,  

 V_{2} = (0.1718 X 0.3556) / 0.1222 = 0.4999 L

The weight of the body in the air is .... the weight of the submerged body
stira [4]

Answer:

the correct answer is option 'b': More than

Explanation:

The 2 situations are represented in the attached figures below

When an object is placed in air it is acted upon by force of gravity of earth which is measured as weight of the object.

While as when any object is submerged partially or completely in any fluid the fluid exerts a force in upward direction and this force is known as force of buoyancy and it's magnitude is given by Archimedes law as equal to the weight of the fluid that the body displaces, hence the effective force in the downward direction direction thus the apparent weight of the object in water decreases.
