Where m and n are statements m n is called the _____ of m and n.
There are infinitely many numbers whose difference is 18 . Every number,say n, differs by 18 from n+ 18 and n -18.
Firstly, the moles of sufluric acid: n=? n=m/Mm=18g = (18)/(98.086)M=98.086 =.18molThefore, there is .18mol per 2 litre (18g in 2L)Therefore, its molarity is .09mol/L
let the number be 'm' & 'n' m + n = 17 m - n = 1 Add 2m = 18 m - 18 / 2 = 9 Substituting 9 - n = 1 9 - 1 = n n = 8 So the two numbers are '8' & '9'.

The surface area of cube M is 6(10 mm)2 = 6(100 mm2) = 600 mm2 The surface area of cube N would be 6(20 mm)2 = 6(400 mm2) = 2,400 mm2
