How many significant figures are in the number 0.0034?

hey!

There are 2 SIGNIFICANT FIGURES!

Explanation:

In the number, the digits 0.00... aren't counted as actual figures (numbers) because they have no value!

So because the digits 3 and 4 have a value higher than 0, they are counted as significant figures... SO THERE ARE 2 SIGNIFICANT FIGURES!!

HOPE THIS HELPS!!

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

personal, she chose to do it.
