Answer: 2.7moles

Explanation:

6Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe

From the equation,

6moles of Cs produced 3 moles of Cs2CO3.

Therefore, 5.34 moles of Cs will produce = (5.4x3)/6 = 2.7moles of Cs2CO3

Calculate the mass of olive oil in a 750mL bottle if the density of olive oil is 0.92 g/mL. *Use the GRASP method.
kap26 [50]

The mass of olive oil : 690 g

<h3>Further explanation  </h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

Given

volume of olive oil = V=750 ml

density of olive oil = ρ = 0.92 g/ml

Required

the mass of olive oil

Analysis

the formula :

\tt m=\rho\times V

Solution

\tt m=0.92\times 750\\\\m=690~g

Paraphrase

the mass of olive oil : 690 g
