#["H"^+] = "0.022 mol/L"#

Explanation:

The formula for #"pH"# is

#color(blue)(|bar(ul(color(white)(a/a) "pH" = -log["H"^+]color(white)(a/a)|)))" "#

We can rearrange this equation to get

#color(blue)(|bar(ul(color(white)(a/a)["H"^+] = 10^"-pH"color(white)(a/a)|)))" "#

If #"pH" = 1.65#,

#["H"^+] = 10^"-1.65"color(white)(l)"mol/L" = "0.022 mol/L"#
