How many moles of solute particles are present in 1 ml of aqueous 0.020 m (nh4)2co3?
Dima020 [189]
Vs = 1.0 mL = 0.001 L
c((NH4)2CO3) = <span>0.02 M
n(</span>(NH4)2CO3) = ?

For the purpose, here we will use the next equation:

c=n/V ⇒ n=cxV

n((NH4)2CO3) = 0.02M x 0.001L 

n((NH4)2CO3) = 2x10⁻⁵ mole of (NH4)2CO3 is presented in the solution

A substance placed in a container has a fixed volume and takes up the shape of the container. In which state does this substance
Tems11 [23]
The substance should be in liquid state.

First, it takes up space in the container, which leads to that it shouldn't be a solid, because solid doesn't change its shape easily.

Second, it has a fixed volume, it's difficult to compress the substance, therefore it shouldn't be gas too, as gas can be compressed easily.

Therefore we're left with liquid. And both of these given properties fits the property of liquid.
