The mass of an average blueberry is 0.75 g and the mass of an automobile is 2.0 * 103 kg. Find the number of automobiles whose total mass is the same as 1.0 mol of blueberries.

Hey everyone, we're asked how many light duty trucks have the same way as one mole of apples, assuming that a light duty truck weighs 2.7 times 10 to the third kilogram and one apple weighs 144 g, Essentially we're going to have to find the relationship between the two. So let's go ahead and start off with our one mole of Apple. We've learned that we can use avocados number for instances like this, So per one mole of apple, we have 6.22 times 10 to the 23rd apples. Again, this is avocados number. And in our questions then we were also told that for one apple, We have 144 g. Now relating this to our light duty truck, we can see that it weighs in kilograms. So let's go ahead and convert this into kilograms. So we know 10 to the third grams is equivalent to one kg and now we can input our 2.7 times 10 to the third kilograms, which we know Is equivalent to one light duty truck. So when we calculate this out and cancel out our units, We're going to end up with a value of 3.2 Times 10 to the 19 light duty trucks and this is going to be our final answer. So I hope this made sense. And let us know if you have any questions
