Many chemistry conferences have held a 50-trillion angstrom run (two significant figures). how long is this run in kilometers and in miles? (1 å = 1 × 10−10 m)

Since, many chemistry conferences have held a 50-trillion angstrom run.

we have to convert this unit into kilometers and miles.

Let us convert it into kilometers first.

Since, 1 trillion =

So, 50 trillion Angstorm = Angstorm

Since, 1 Angstorm =

So, 50 trillion Angstorm =

=

So, 50 trillion Angstorm = 5km

Now, we will express it into miles

Since, 1 mile = 1.61 km

So, 5 km =

= 3.105 miles

= 3.11 miles

So, 50 trillion Angstorm = 5 km = 3.11 miles

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

i think its a and d
