How many decades are in 6.02 x 10^23 seconds

6.02 x 10²³ seconds ≈ 1.909 x 10¹⁵ decades

Explanation:

Second is the SI unit of time, which is denoted by the symbol s. In one minute there are 60 seconds.

So, in one hour there are 60 mins = 60 × 60 seconds = 3600 seconds.

In one day there are 24 hours = 24 × 60 minutes = 24 × 60 × 60 seconds = 86,400 seconds.

In one year there are approximately 365 days = 365 × 24 hours = 365 × 24 × 60 minutes = 365 × 24 × 60 × 60 seconds = 31536000 seconds.

Since, a decade is defined as the period of ten years.

So, a decade = 10 years = 10 × 365 days = 10 × 365 × 24 hours = 10 × 365 × 24 × 60 minutes = 10 × 365 × 24 × 60 × 60 seconds = 315360000 seconds.

Since, 315360000 seconds = 1 decade

Therefore, 6.02 x 10²³ seconds = 6.02 x 10²³ seconds ÷ 315360000 seconds ≈ 1.909 x 10⁻⁸ x 10²³ = 1.909 x 10¹⁵ decades
