1 answer:
salantis [7]2 years ago

Answer:

Explanation:

This is not the exact definition of a formula unit, but I think I know what is meant. You want the number of mols that 33.8 grams represents.

1 mol of SrF2

1 unit of Sr =                     87.62

2 units of F = 19.00 * 2<u> = 38.00</u>

1 mol of SrF2          =       125.62

mols SrF2 = given mass / molar mass

given mass = 33.8

Molar mass = 125.62

mols = 33.8/125.62  = 0.269

Write the chemical formula for sodium hypobromite.
irga5000 [103]

Answer:

             NaOBr  (or)  Na⁺ ⁻OBr

Explanation:

The Oxo-Acids of Bromine are as follow,

                           Hypobromous Acid  =  HOBr

                           Bromous Acid  =  HOBrO

                           Bromic Acid  =  HBrO₃

                           Perbromic Acid  =  HBrO₄

When these acids are converted to their conjugate bases their names are as follow,

                           Hypobromite  =  ⁻OBr

                           Bromite  =  ⁻OBrO

                           Bromate  =  ⁻OBrO₂

                           Perbromate  =  ⁻OBrO₃

According to rules, the positive part of ionic compound is named first and the negative part is named second. So, Sodium Hypobromite has a chemical formula of Na⁺ ⁻OBr or NaOBr.
