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

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
