100 মিলি `H_(2)` গ্যাস 10 সেকেন্ডে ছড়িয়ে পড়ে। `O_(2)` গ্যাসের X mL টি সেকেন্ডে ছড়িয়ে পড়ে। X এবং `t` হতে পারে না

100 mL of H_(2) gas diffues in 10 sec. X mL of O_(2) gas diffuses in t sec. X and t cannot be

If 100 mL of H_(2) SO_(4) and 100 mL of H_(2)O are mixed, the mass percent of H_(2) SO_(4) in the resulting solution (d_(H_(2)SO_(4)) = 0.09 g mL^(-1), d_(H_(2)O) = 1.0 mL^(-1))

2H_(2) O_(2) (l) rarr 2H_(2)o(l) + O_(2) (g) 100 mL of X molar H_(2)O_(2) gives 3L of O_(2) gas under the condition when 1 moe occupies 24 L . The value of X is

50 mL of 1 M HCl, 100 mL of 0.5 M HNO_(3) , and x mL of 5 M H_(2)SO_(4) are mixed together and the total volume is made upto 1.0 L with water. 100 mL of this solution exactly neutralises 10 mL of M//3 Al_(2) (CO_(3))_(3) . Calculate the value of x .

100 mL O_(2) gas diffuses in 10 sec. 100 mL of gas X diffuses in t sec. Gas X and time t can be
