[tex]F = m*a[/tex]
[tex]1.05N = m*3.5\frac{m}{s^2}}[/tex]
[tex]\frac{1.05}{3.5} = m[/tex]
[tex]0.3kg = m[/tex]
We know, Force = mass * acceleration
Here, f = 1.05 N
a = 3.5 m/s²

Substitute their values, 
1.05 = m * 3.5
m = 1.05 / 3.5
m = 0.3 Kg = 300 g

In short, Your Answer would be 300 gram

Hope this helps!
