The mass of an average blueberry is 0.75 g and the of am automoblie is 2.0 x 10 to the 3 Kg. Find the number of automobiles whos
Paul [167]

Answer : The number of automobiles needed are, 2.26\times 10^{17}

Explanation :

First we have to calculate the mass of blueberries.

As, 1.0 mole of blueberries contains 6.022\times 10^{23} blueberries

So, 0.75 grams of blueberries contains 0.75g\times 6.022\times 10^{23}=4.52\times 10^{23}g blueberries

Mass of blueberries = 4.52\times 10^{23}g

Now we have to calculate the number of automobiles needed.

Number of automobiles needed = \frac{4.52\times 10^{23}g}{2.0\times 10^{3}kg}

Number of automobiles needed = \frac{4.52\times 10^{23}g}{2.0\times 10^{3}\times 10^{3}g}

Number of automobiles needed = 2.26\times 10^{17}

Thus, the number of automobiles needed are, 2.26\times 10^{17}

Pepsi [2]

Answer:

0.454moles

Explanation:

Calculate the molar mass of AgBr

Ag=108

Br=80

Molar mass= 108+80

Molar mass=188g/mol

It's mole to gram question

2moles of Na2S2O3= 188g of AgBr

X moles of Na2S2O3=42.7g of AgBr

Cross multiply

188x=2×42.7

X= 85.4/188

X=0.454moles
