How many total atoms in the following formula: 5H3PO4

12 is probably the typical age for a first kiss but i think its to young.

The velocity would be 2 

Ithink b not to sure hope that : )

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
